I have an 04 6 speed car and I am the second owner. I got service history on the car when purchasing it. It had the original engine in it at 64k when I purchased it. At 82k I replaced the engine. It started getting an MIL for a front rotor misfire on cold starts and would smoke. Then began smoking more and more, but nothing spectacular. I knew it was coming, I knew the engine was going out. I knew that the failure rate decreased as production models went. I live 45 minutes from Rotary Resurrection and planned on having the engine rebuilt by Kevin prior to the engine failing completely. I drove my MSP for a couple of weeks and didn't touch the 8. Then I started driving the 8 again. A couple of days later, I lost compression on the front rotor and due to the nature of the beast, knew that the front rotor and rotor housing were probably damaged. I started looking at the cost for rebuild from RR ($1,600) and the warranty (12mo./Unlimited mileage) versus that of a used engine from an 07/08MY car and made the decision to get an engine that had the revisions done. I was able to source a 51k engine from an 07MY car with a 1yr/unlimited mileage warranty for $1775. I am a service manager at a shop and a former technician, so I R&R'd the engine myself in 6.5 hours. There are a few differences in the crankcase ventilation system, but the main difference was within the powertrain management and the volume of oil that is injected into the engine that helped the engines in the later years last longer.
